Most Helpful Negative Review Could Be Better
I purchased the “Ultimate Trigger” for my 22/45. The stock trigger was not to good. Got this installed professionally and it is better but not as good as I was expecting. I like the flat shoe, but it could be a little lighter.

Quality Tigger Upgrade

by artz, Verified Owner from VA, United States Written on April 3, 2026
TANDEMKROSS definitely makes quality trigger upgrades. This kit reduced my sloppy 5lbs. trigger to a very smooth 3lbs. It has plenty of adjustment for taking up the pre and post travel. Watch the video a few times and the upgrade will go smoothly. I definitely recommend this upgrade.

Works as Advertised

by Joe, Verified Owner from MT, United States Written on January 4, 2026
The trigger kit does reduce pull. Installation is much easier with a vise holding the frame after you remove the grips. Needle nose pliers are a must.
Pros:
  • Works & fits great
Cons:
  • Instalation time
Would recommend: Yes

  • Light trigger and great reset
  • build quality and function
Cons:
  • None
Best Used for:
  • Competition Shooting

Excellent Trigger

by RonGT, Verified Owner from VA, United States Written on January 10, 2025
Installed the Ultimate Trigger Kit on a Ruger MKIV Tactical. Installation was a little tricky but found help on Youtube. After installation, I was able to easily adjust the trigger to my liking and it performs well. The Ruger has a decent trigger but this kit makes the pistol much better. I highly recommend it!
Pros:
  • Easy adjustment
Cons:
  • None
Would recommend: Yes

Excellent Trigger

by RonGT, Verified Owner from VA, United States Written on January 3, 2025
This is my second TandemKRoss Ultimate Trigger Kit. Recently picked up a Ruger MKIV 22/45 and based on my experience with the trigger kit installed in a Ruger MKIV Target with a lot of use, this was the first thing I wanted to install in the 22/45. Have never had a single problem with the trigger in my MKIV Target and I like having the capability to adjust the trigger to my preferences. The parts are well made and replaced the OEM parts perfectly. Overall, I highly recommend this trigger.
